The kinetics of pearlite transformation in Fe-0.5mass%C steel has theoretically been investigated based on the system free energy theory proposed by us, by which the kinetics of phase transformation for each phase can be estimated according to its energy priority. The interlamellar spacing of pearlite is precisely predicted by the energy analysis, and the calculated time -temperature- transformation diagrams consist with the experimental ones. It is obvious that the system free energy theory is also effective for analyzing the lamellar structure produced by, e.g., the pearlite transformation in steel.
